- 1What is an atom is made up of?An atom is made up of protons, neutrons and electrons. The protons are positively charged and electrons are negatively charged.
- 2Describe the location of the subjects in an Atom?The protons and neutrons are found in the nucleus, the electrons are arranged in shells around the nucleus.
- 3How come the Electrons doesn't float away?Electrons are held in place by electrostatic forces.
- 4Describe how many electrons the first, second and third shell can hold?The first shell has room for 2 electrons, the second and third shells, 8 electrons
